Another Boston resident said she doesn't "notice anything," when it comes to racial disparity.

Boston Police tell NECN they initiated an independent study four years ago to learn more about police interrogations on the streets, and included the ACLU from the beginning.

They say the findings show the department is focused on the areas most responsible for violent crime. They also admit that while the study did find racial disparities, they were unable to determine what caused them and say they are committed to reducing all disparities.

"The Department believed the ACLU shared this philosophy, however, their actions over the past 24 hours have shocked and surprised the Department. When asked last evening to participate in a joint announcement today to inform the public of the preliminary findings, the ACLU replied that it was not prepared to announce any findings."
